The result is an incorrect air - fuel mixture than can create a number of problems, such as hard starting, a rough idle, hesitation, misfiring or a drop in fuel economy — issues that could, without proper diagnosis, seem to have other causes, such as incorrect ignition timing or fouled spark plugs.

The camshaft position sensor is a magnetic sensor that monitors camshaft speed to regulate ignition timing and fuel injection timing.

If the timing belt is slipped it can impact ignition timing, which will effect whether or not the vehicle can start.

But I do know that there are a lot of variable timing systems out there these days even without boost, like mivec, vvt, the BMW method (whatever it's called), and others, and a lot of them focus on drastically changing ignition timing based on sensor data, even if theres no actual valve timing changes (like vtec).

A MIL may also be on, with DTC P050B (cold start ignition timing performance) stored.

In the US, federal emissions regulations forced a reduction in ignition timing and compression ratio, resulting in a lower power output (140 hp)[citation needed] for the 260Z despite the additional displacement, whereas in other countries the power output increased to 165 bhp (123 kW; 167 PS).

But with all our advanced EFI and ignition timing electronics, is this still an issue?

Bad ignition time is another, as is bad valvetrain timing.

The brainboxes at Mazda seem to have solved the issue of compression ignition timing, using a little device called a spark plug.

The first one is the TDC you're looking for when concerning ignition timing.

I had another look at my Subaru's mapping and saw that there are more ignition timing tables than I first thought.

But ultimately, you'd need to run your car on a dynamometer to find the best spark plug gap, and the right ignition timing for your engine.

A misfire occurs when a cylinder fails to ignite the air / fuel mixture at the right time and could happen due to a wide range of reasons, including lack of spark (a bad coil), lack of fuel delivery (clogged fuel injectors) and improper ignition timing (out - of - spec cam timing).

There's still a 3.8 - litre, twin - turbocharged V6, but thanks to new ignition timing and more boost from the turbochargers it now develops 562bhp and 470 lb ft of torque, up from 542bhp and 466 lb ft. Tamura points out Nissan's ethos of «line management» - while more power is possible from the V6, the company is much more concerned about making its power accessible throughout the rev range.

This affects ignition timing which can...

This, together with more aggressive ignition timing, equates to the new enhanced output.

Optimal ignition timing is set due to improved knocking resistance created by a highly efficient radiator and a water jacket that efficiently cools the combustion chamber.

Under the hood, GT - R carries over the same 3.8 - litre twin - turbo V6 unit, but some fiddling with the ECU and ignition timing means that it now produces 565 HP of power and 637 Nm of torque.

This data is used to alter ignition timing to reduce the problem

The larger turbochargers deliver improved breathing, while optimized performance tuning provides precise ignition timing and an upgraded fuel pump supplies the additional fuel needed for the correct air / fuel mixture.

Mazda utilizes a lightweight rotating assembly (crank, rods, pistons), high 13 to 1 compression ratio (for added horsepower), automatic ignition timing (to prevent detonation), individual tube exhaust headers (for better performance and mileage) and an enhanced 6 - speed automatic (that is geared for both get up and go and fuel economy).

A powertrain control module (PCM) examines various engine functions as well as a block - mounted acoustic knock sensor to determine optimum ignition timing.

Subaru addresses this problem by altering the programming in the Engine Control Module to delay ignition timing, making the exhaust gasses hotter, which helps the catalytic converter heat up sooner, reducing emissions.
